Andy Murray will return to singles competition for the first time since January when he faces Richard Gasquet at the Cincinnati Masters on Monday.
The Briton, 32, lost in the first round of the Australian Open in January and broke down in tears amid fears a hip injury may end his career.
He underwent hip resurfacing surgery and has since played in doubles events.
Murray - now ranked 325 in the world - is expected on court around 19:00 BST against world-number-66 Gasquet.
Murray gained a wildcard entry and speaking on the eve of the tournament the three-time Grand Slam winner said he has had "good" results against top players on the practice court.
